PRAVEEN KATHIRVASAN Intensive care units (ICU) have been critical for treating those severely ill with COVID-19. This branch of medicine deals with the process of temporarily supporting and replacing the function of multiple organ systems during serious illness and trauma. The first intensive care unit in Europe was set up by Bjørn Ibsen, an anaesthetist whose experimental form of positive pressure ventilation was pivotal in the intervention of the 1952 poliomyelitis epidemic in Copenhagen. Today, intensive care is considered a stand-alone speciality with the establishment of the Faculty of Intensive Care Medicine in 2010.
